• Brushless DC Motors
  motors generally contain a three-phase winding, although some operate four phase. Brushless motors powering small fans and other constant-speed equipment are often two phase. Power for brushless motors generally is a trapezoidal ac wave form, but some of the motors operate with sine waves...
• Switches put a new spin on motors
  . A potentiometer or keypad manually controls the motor, or a transducer or serial link can provide automatic control. The motor combines features of ac and dc motors but also has unique characteristics. Its salient-pole stator is similar to a dc machine and does not create a rotating field, as used...
• Solar-powered UAV flies two days straight
  An electric-motor driven UAV (unmanned aerial vehicle) recently completed a 48-hr nonstop test flight using only solar energy. The SoLong unmanned aerial vehicle from AC Propulsion recently flew over 48 hr nonstop fueled only by solar energy. The plane sports a wingspan of 4.75 m and weighs 12.6 kg...
• Zap! Hydraulic filters thwart shocking behavior
  An electric-motor driven UAV (unmanned aerial vehicle) recently completed a 48-hr nonstop test flight using only solar energy. The SoLong unmanned aerial vehicle from AC Propulsion recently flew over 48 hr nonstop fueled only by solar energy. The plane sports a wingspan of 4.75 m and weighs 12.6 kg...
• The importance of not being first
  that companies first in the market don't seem to endure over the long term. In fact, it might be an advantage not to be first. Let's look at some companies that were first with innovations but which either no longer exist or have a minimal presence in the field today. First company to market ac electricity...
• Metal-faced sensors
  industrystandard housings with ac or dc outputs at a cost competitive with traditional models. Just how much longer do metal-face proximity sensors last compared to plastic-face sensors? Abrasion testing at determined that a stainless-steel sensing face that was 0.4-mm thick prolonged sensor life over 20...
• Readers Tell Us How We've Helped
  , the windows to the fiberglass frames, and the interior trim." he says. "And that knowledge still comes in handy when specifying and evaluating fasteners we use to put together 50 to 100 metal enclosures each month to house custom-manufactured transformers, inductors, and ac/dc power supplies. Plus, I...
• Best Sites on the Web
  to its complete catalog of automation products from ac drives to wiring systems, the Automation Direct Web site includes a comprehensive technical support area. Engineers can get technical and application notes, cable wiring diagrams, online user manuals and instructions, compliance documents...
• Sensor Sense: Hall-effect current sensors
  applications, or any applications in harsh environments. There is no electrical connection between the current path and sensor and, unlike current transformers, Hall-based sensors measure dcas well as ac currents. Hall-effect current sensors measure the strength of the magnetic field generated...
• Humidity sensors
  , or treated substrate. Hygroscopic means the material readily absorbs water — in this case from the air. Placed between two noble metal electrodes, the conductivity of the material changes with the amount of water absorbed. A zero-centered ac voltage is used to measure the conductivity to prevent polarization...
